According to Politico, Newt Gingrich is 2012 Republican candidate to watch on Twitter.
As Emily Schultheis noted yesterday, Gingrich who has been using the social media service since Februrary 2009, is leading the pack of Republican contenders. From her piece:
"Gingrich has a whopping 1.3 million followers on the popular social media site. His three closest Twitter rivals from the 2012 GOP presidential field, former Massachusetts Gov. Mitt Romney and Reps. Ron Paul and Michele Bachmann, all hover around 60,000 followers apiece. Even Twitter enthusiast Sarah Palin, who hasn’t indicated whether she’ll run, has less than half the followers Gingrich does."
